The aim of the present pilot trial was to investigate the effects an exercise program consisting of eccentric training and static stretching exercises combined with High Intensity Light Therapy (HILT) in patients with Chronic Patellar tendinopathy (CPT). Eight patients who had CPT participated in the present pilot trial. They received an exercise program consisting of eccentric training and static stretching exercises combined with HILT. All patients received an exercise programme five times per week for four weeks. Patients were treated with HILT for 3 sessions per week for 4 weeks, 12 sessions in total. Pain and function were evaluated using the VISA-P score at baseline, at the end of treatment (week 4), and one month (week 8) after the end of treatment. At week 4, there was a rise in VISA-P score of about 37 units. This rise is maintained at the one month follow-up. The results suggest that the combination of an exercise program with HILT is an adequate treatment for patients with CPT. Further research to establish the relative and absolute effectiveness of such a treatment approach is needed.
